Information leading to the delineation of this focus area

Basis for focus area Basis is currently speculative, but the resource has been reported.
Identified resources Identified resources of heavy mineral sands.
Production None.
Status Unknown.
Estimated resources Unknown.
Geologic maps Clark and others (1993), scale 1:500,000; Approximately half of the 7.5 minute (scale 1:24,000) geologic quadrangles maps have been completed for this area.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Tertiary Wilcox Formation and Claiborne Group.
Deposits None.
Evidence from mineral occurrences Presence of heavy mineral sands have been mentioned in some reports.
Geochemical evidence Some data may exist in unpublished Tennessee Geological Survey Mineral Resources Collection files.
Geophysical evidence None.
Evidence from other sources Geologic mapping.
Comments Prior investigations of the mineral resource potential are lacking for these Tertiary-age deposits.
Cover thickness and description Uncertain; may be estimated from available water well logs in the area.
